Thick or thin

I felt a bit like I have been back in my senior year of high school this past week. We applied at a local private school for my son, who will start kindergarten in the fall. The school is beautiful, small and they have some wonderful programs. The uniforms are an added bonus. Anyway, letters of acceptance were to go out this month and I've been running to the mailbox every day hoping for a letter. Today we got one. I looked at the envelope and it was pretty skimpy -- the Web site said that the acceptance letters would also contain the registration agreements. But the envelope didn't look like it could contain much. I was shaking as I opened the letter... Congratulations, we'd love to have Lucas at our school for the 2008-2009 school year!
We got in! Now there is the little issue of tuition. It's about $7500/year. I'm paying more than that for preschool right now, but if we go to the local public school, I'll pay nothing.
I just get such a good vibe from this Episcopal school and feel that Lucas would really thrive there.
What to do....
I've got about 10 days to make a decision and then talk Phil into agreeing with me.
